The Terminator franchise prided itself in having killer robots sent from the future attempting to kill the future leader of the resistance. Let’s not forget the interesting family dynamic. This has been the premise for at least four of the Terminator films. The fifth, Terminator Genysis, see Kyle Reese go back to the past once again, but Sarah Connor and the Terminator already anticipated his return.

However, a new trailer from the Alan Taylor-directed film gives more story and puts a twist in the Connor family dynamic as John is also sent back to the past, and he isn’t what he appears to be. Hit the jump to see the second trailer for Terminator Genysis.

The first trailer and Super Bowl TV spot made it seem like the only twist to this was that Sarah Connor and the Terminator knew Reese was coming, and so he wouldn’t need to convince her of the impending threat. But in this trailer, the twist is that John Connor travels to the past, but his intentions aren’t the same. In fact, he isn’t even really human.

Now that John has become the very thing that Sarah is trying to kill, does she have the heart to to kill her own son to save the future? Again, interesting family dynamic, and a twist that was withheld until now.

When John Connor (Jason Clarke), leader of the human resistance, sends Sgt. Kyle Reese (Jai Courtney) back to 1984 to protect Sarah Connor (Emilia Clarke) and safeguard the future, an unexpected turn of events creates a fractured timeline. Now, Sgt. Reese finds himself in a new and unfamiliar version of the past, where he is faced with unlikely allies, including the Guardian (Arnold Schwarzenegger), dangerous new enemies, and an unexpected new mission: To reset the future…
